HENRY IVHITE, OF MARION, OHIO.

SMOKE-CONSUMER.

SPECIFICATION forming part of Letters Patent N 766,749, dated August 2, 1904:.

Application filed April 8, 1903- Serial No. 151,679. (No model.)

To ail whom it may concern.-

Be it known that I, HENRY WVHITE, a citizen of the United States of America, and a resident of Marion, county of Marion, and State of Ohio, have invented certain new and useful Improvements in Smoke-Consumers, of which the following isa specification.

My invention relates to a device which is adapted to consume smoke by providing a means of mixing the air and gas.

The objects of my improvement are to afford facilities for drawing the air through airducts provided in a plate or mixer forming the back wall of a furnace in such a manner as will bring the air to the center of the volume of gas as the latter is passing out. It is well known that the gas which is generated from the fuel is colder and will not mix with the hot air.

In the construction of back or bridge walls of the ordinary type there is no means provided for the admission of cold air to counteract the efi'ect of the gases. By the construction of the back plate as described hereinafter it will be noted that means for the admission of cold air is provided, insuring a thorough mixture of the air and gas, which is immediately ignited, burning the gas and consuming the smoke. This has the effect of producing a continuous flame under the boiler and assisting in the generation of the steam to a considerable extent, thereby resulting in a great saving of fuel. I attain these and other objects by the construction of the device shown and illustrated in the accompanying drawings, in which Figure 1 is an end elevation of a boiler, showing a front view of my mixer or back plate as applied to the boiler. Fig. 2 is a side .view of the mixer or back plate, showing it applied to a boiler and the means for the admission of air. Fig. 3 is an isometrical view in perspective, showing the elevations of the air-ducts.

Similar letters refer to similar parts throughout the several views.

Reference-letter a designates an ordinary horizontal boiler. The lower end of the inclined back plate or mixer c is suitably supported by the brickwork of the furnace adjacent the rear end of the grate. The opposite end of the mixer is supported by the brickwork, as shown in the drawings. Depending flanges are formed integral with the mixer and are adapted to overlap the side plates 0. These side plates are secured to both sides of the mixer, (only one side being shown in the drawings.) Doors f are hinged to the side plates, the doors being provided with an adjustable air-inlet g, fitted to each door in such a manner as to permit of more or less air being drawn through the apertures. It will be noted that the air is drawn in under the mixer and passes out through the airducts (Z. The air-duets are made integral with the, mixer and project above the surface or plane of the body portion of the mixer. The air-ducts are formed in the mixer in alternate series, as shown, having the largest openings at the top and gradually tapering therefrom for the purpose of keeping the walls of the air-ducts free from soot, ashes, &c. The air-ducts are made to project above the plane of the body portion of the mixer for the purpose of permitting the ashes to fill in the spaces between the air-ducts. It is well known that ashes are a non-conductor of heat, and as the ashes are deposited upon the surface of the mixer it has the effect of keeping it cool, thereby preventing the mixer from becoming warped or burned by excessive heat. As the air is admitted through the inlet r it passes under the mixer and is drawn out through the apertures providedin the mixer, the air-ducts being elevated so as to bring the outlets of the air which passes through the mixer to the center of the draft or travel of the hot air and gases, neutralizing the temperature of the hot air and permitting the air and gas to mix and ignite, producing a continuous flame, whereby the smoke and gas are consumed.

Slight changes or modifications of my device can be made without deviating from the principle of my invention and by means of the flanges of the back plate, theside plates 10 which my device can be applied to any appaprovided with openings therein and means ratus for the purpose of consuming smoke. for closing the openings.

WhatI claim as my invention, and desire to Signed at Marion, Ohio, this 1st day of 5 secure by Letters Patent, is- April, 1903.

An article of manufacture comprising a HENRY WHITE; back plate having air-ducts projecting above Witnesses: the surface thereof, the plate provided With JOHN F. MONEAL,

depending flanges and side plates engaged by HORACE JOHN OoBBoLD.
